SIZING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 740,180, datedSeptember 29, 1903.

Application filed October 11, 1902. Serial No. 126,945. (No model.)

To all whom it may concern: Be it known that we, EDWARD RETTIGH, ofGermantown, and MILTON E. PUGH, of Dayton, in the county of Montgomery,State of Ohio, citizens of the United States, have invented certain newand useful Improvements in Sizing-Machines, of which the following is aspecification. Our invention relates to sizing-machines, and moreespecially to sizing-machines that will separate articles according totheir length.

Our invention is particularly adapted for use in sizing tobacco-leaves,but may be used in separating like articles according to length.

The object of our invention is to provide a machine, automatic in itsoperation, that will do the work in a simple, efflcient, and accuratemanner and with the least possible damage to the articles being sized.

\Vith these and other objects in view our invention consists of theconstructions and combinations of parts hereinafter described, and setforth in the claims.

In the accompanying drawings, which form apart of this specification,Figure 1 is a plan View of a machine embodying our invention. Fig. 2 isa detail, partly in section, of the butting devices. Fig. 3 is a detailshowing the relation of the inclined conveyors to the butting device andthe means of driving said conveyors. Fig. 4: is a detail of the feedingdevice; and Fig. 5 is a transverse section of the bins, showingthesizing-rolls and carrier in said bins, taken on the line a: a: ofFig. 1.

Like parts are represented by similar letters of reference in theseveral views.

In the accompanyingdrawings, a represents a frame, and h and b cushionedrolls mounted on shafts suitably journaled in the respective ends ofsaid frame. Said rolls are preferably made of flexible or pliablematerial that will cushion on and not bruise the leaves passing throughsame, or said rolls may be covered with such material for the purposenamed. In the rear of the sizing-rolls we arrange a series ofsizing-bins having partitions a, each bin being adapted to receivedifierent lengths of the article sized. Extending from the rear of thesizing-rolls and projecting into said bins we provide carriers a whichrun upon rolls a and a extending longitudinally through said bins. Thesecarriers are inclined upwardly at their rear ends, so that the leaveswhich travel tip first in passing from the carrier will bend downwardlyand the butt-ends of the leaves, being stifier and heavier, will bethrown over, thus turning the leaves end for end and dropping them intothe bottom of the bins, as shown in Fig. 5. The articles pass from thesizing-rolls to said carrier over a plate-0. At one end of saidsizing-rolls and substantially at right angles with same wearrangefeeding and butting devices. On a feeding-board c we arrange a casing c,in the bottom of which we provide a carrier carried by rolls 0 and c andwe further provide in a housing 0 at the end of said casing two rolls 0and 0", preferably formed of material used for the sizing-rolls, ashereinbefore described, said carrier-rolls delivering the articles to besized into the butting-machine, which consists of a flexible conveyorol,'having a link belt d, mounted on sprocket-wheels d and d said linkbelt and sprocketwheels being provided at each end of the butter andcarrying between same partitions d", provided with bottoms, so that therotation of said butter will carry the article to be sized within thecompartments or bins formed by said partitions. A casing may be providedto cover said butter; but it is only essential that a casing such as d,extending about the lower portion of the butter, as shown, be provided.

Immediately underneath the devices just described and at right anglesthereto we provide a carrier (1 the casing being open over said carrier,so that as the articles within the bins formed by said partitions passover said carrier said carrier will butt their ends against a wall dUnderneath the carrier d, as more particularly shown in Fig. 3, andextending at an inclination to the sizing-rolls b and b, as shown inFig. 1, we provide a series of conveyers e. The ends of the conveyors eadjacent to the sizing-rolls are carriedby rollers journaled inthe'frame a, said rollers not being shown, but each is limited in lengthto the width of the belt it carries, and the opposite ends of saidconveyors are carried by a roll 6 common to all of them, said lastnamedroll being the driving-roll for said conveyers. The construction is suchthat the carrying portions of the belts between the individual rolls andthe driving-rolls are free to ride on said frame, as shown in Fig. 5. Itwill thus be seen that as the leaves or articles come from thebutting-machine with one of their ends adjusted against the wall (1 andare delivered to the conveyers they will be carried along by the conveyers until each leaf or like article is, according to its length,

- caught by the sizing-rolls and carried to the respective bins, asparticularly shownin Fig. 1.

The conveyers may be driven in any suitable manner; but we have shownthe same driven by a grooved pulley 6 which receives its power by around belt from any suitable line-shaft, said pulley being mounted upona shaft 6 which drives the roll (2 through a pair of bevel-gears 2 Theupper sizing-roll is driven by-a pulley b which may receive its power bya belt from the same line-shaft as the pulley e and the carrier a isdriven by a belt a", extending from a pulley b to a pulley a on theshaft of the roll 0. On the shaft of the roll a we also mount twogrooved pulleys a and a one of which, a carries a round belt to agrooved wheel 01 to drive the sprocket-wheels d and cl of the flexibleconveyer, said belt extending about a well-known form of idler-pulley,(not shown), and from the grooved pulley a we drive the carrier d by around belt extending directly to the grooved pulley d of the carrier dOn the shaft of the sizing-roll b we mount three grooved pulleys a a,and a, a having a round-belt connection to a pulley c to drive thecarrier 0 a a round-belt connection to the pulley c to drive the rolls 0and c and 0. has a round-belt connection about an idler-pulley (notshown) to a pulley f to drive a brush f. The brush f extends over thebins or compartments of the flexible conveyer, so that when the articlesto be sized are fed to said flexible conveyor if for any reason one ormore of them should be caught on the top edges of the partitions theywill be swept off into .the compartments or bins. The extension d of thecasing for the flexible conveyers catches the articles that are beingfed and directs them into the bins.

The operation of the machine is as follows: The leaves or articles to besized are fed through the feeding device into the compartments or binsof the flexible conveyer, and they are carried by the flexible conveyoracross the carrier underneath the same, which is traveling at rightangles to said flexible conveyer, so as to adjust one end of all thearticles and deliver them to the conveyers, by which they are carriedforward, and the conveyers being arranged at an inclination to thesizing-rolls the articles will reach these rolls according to theirlength and be gathered by said rolls and carried into separate bins,according to their length.

Having thus described our invention, we claim' 1. The combination with aframe and sizing-rolls, of a conveyer, the carrying portion of which isadapted to travel on the surface of a stationary portion of said frame,at an angle to said rolls, substantially as specified.

2. The combination with frame and sizingrolls, of a series ofconveyor-belts, the carrying portions of which are adapted to travel onthe surface of astationary portion of said frame at a uniform speed andat an angle to said rolls, substantially as specified.

3. The combination with a-frame and sizing-rolls, of a series ofconveyor-belts operating in the same plane, the carrying portions ofwhich are adapted to travel on the surface of a stationary portion ofsaid frame at an angle to said rolls, and means to locate the articlesto be sized on said conveyor-belts, substantially as specified.

4. The combination with sizing-rolls,of conveyers adapted to travel atan angle to said rolls, and means, including devices to move thearticlesto be sized in two directions and deliver same to said conveyers,substantially as specified.

5. In a machine such as described, butting devices consisting of aseries of bins running over a carrier which travels at right anglesthereto, substantially as specified.

6. The combination with sizing-rolls and conveyers adapted to travel atan angle to said rolls, of butting devices consisting of a series ofbins running over a carrier which travels at right anglesthereto,substantially as specified.

7. The combination with sizing-rolls and feeding and butting devicesarranged substantially at right angles to said rolls, of conveyerstraveling obliquely from said butting devices to said rolls,substantially as specified.

8. The combination with sizing-rolls and a series of sizing-bins in therear of said rolls, of carriers extending from said rolls and in clinedupwardly to carry and drop the articles sized into their respectivebins, substantially as specified.

9. The combination of sizing-rolls with sizing-bins in the rear of saidrolls with carriers extending from said rolls into said bins, feedingand butting devices arranged at substantially right angles to saidrolls,and con veyers traveling obliquely from said butting devices to saidrolls, and means to drive said parts from a common source of power,substantially as specified.

10. The combination with a frame and a' rollers for each belt at theother end of said conveyer journaled in said frame adjacent to saidsizing-rolls, each of said last-named rollers being limited in length tothe width of the belt that operates over it, whereby the carryingportion of the belts between the driving and the individual rollers rideon said frame, for the purpose specified.

11. The combination with a frame and a pair of sizing-rolls, of a seriesof parallel endless conveyer-belts of different lengths operating in thesame plane at an angle to said rolls, a driving-roller at one 'end of?said conveyer common to all of said belts, individual rollers for eachbelt at the other end of said conveyer journaled in said frame andadapt- EDWARD RETTIGH.
